To all 'whom 'it may-concern:

le it known that I, GEORGE E. KNEPrnR,

a citizen of the UnitedStates, residing at Altoona. in the county .of Blair and State of Ieiinsyl\'ania,'liave` invented certain new and useful Inipiove'inent's' inv Car-Roofs, of which the. following isa specification.v

This invention relates to an improved water-tight metallic roofing *for railway ve'- liicles.' rz' I" General objects vof"the'invention are'to f provide a car-rooting wlii'clifgobviates Ithe use of any metallic strips; eaps',f.orf.lionsing`s lother thaiitlie metal roofing sheets 'themselves, and to so .construct the end the joints as to set back fromfthefe'dge of the cari' A further @meer 'of .aie 'invention' -i's i0- provide lmeans whereby the :individual -sliets of the roofv very practical vway to the life of the sides ofthe car. the paint, and-the prevention of damage -to the goods `inside the ear.

With the above and various otherobjects in view which will more :readily appear as the nature of tlieinvention is' better understood. thesanie consists -in the-nove1 conf struction, combination. and arrangement. of parts as are hereinafteimorefully pointed out, illustrated-and claimed.' f

I t will be readily understood that the 'arious structural features of the invention.

are susceptible to modifications without departing from t-lie scope of the invention, but

certain preferred embodiments of the saine are shown in the accompanying drawings, wherein:

Figure 1 is a perspective view of a portion ot a car, the roof ofthe same having tlieimproved covering applied thereto. Fig. 2 is a detail perspective View of a ortion of a car roof showing the manner o making the joint at the eaves thereof. Fig. 3 is a. view similar to Fig. 2, but showing a. modifica.- tion thereof. Fig. 4 is a det-ail perspective View of a still further modification ofi the joint shown in Fig. 2. Fig. 5 is a detail perspective view,.partly in section showing Vthe 'joint between the sections ofthe covering at the center ofA the car roof. Fig. 6 is an Specification of Letters Patent.

In applying the improved roof covering framinggii'bifgi flic sides of the car.'thus." contributing in a very practical way to'gits l The improved roofing is made un of recv ta-ngnlar ,matching metal sheets 11 joined together b vtransverselongitudinalseams 12 12 are made by the union ot two adjacent sheets 11 whoseedges are bent i'nto- :ipproximateliv inverted U-sliaped beads 14 and 8". As shown in the figures of the drawi At the eaves 15 of the car body the inter- .95

back as best shown at 16 in Fig. 1 to provide Vbent as shown in that ligure, it is cut so as' to permit an offset leg. 19 to engage with a keeper notch 22 previously made 1n the sheet.

4After the'leg 19 is placed in position, the

seam closing wing is bent back to the inverted U-shaped joint, and the top portion 23 is flanged over the joint 12 as shown in the drawings.

Previously to turning the edge 23 over the top ofthe joint 12, the auxiliary filling strip 24 is placed in position, after which the ends 17 of the sheets are secured to the side of the car as plainly shown in Figs. 2, 3 and 4.

In addition to constructing the roof in thismanner, the edge 26 of the facing board 27 is undercut to provide an edge 28 that is lower than the edge 29 adjacent to the car.

: This construction causes the water to drip from the edge 28 without. running down-the side 30 of the car.

In the modified form of the joint shown in Fig. 3, an integral seamsclosing plate 20 drawin is employed whose base 20b has its end por-A tions clam ed beneath the opposite legs 17.

A still' urther modification is shown in Fig. 4, in which the sheet 24 is formed with the struck up central rib 31 which gradually slopes oil as at 32 and merges into the sheet 24, thus forming a seamclosing plate 32.that

prevents the penetration of snow, ice and wate r.- 1.4 i

The union of the four sheets atthe top o f thecar is'illustrated in Fig. 5 of the As shown, the sheets 11 are held by the binding bolt 34 which lpasses through the bindingA b car. And, as shown in Figs.' 6 and 13 it will be seen that the vplates are provided with corner lips 33 and l37 respectively. to form a pan shaped structure which readily fulfils the purpose for which it was designed.

lA modified form of union of the four corners of the sheet 11, at the top of the'car is shown in Fig. l1 in which the saddle block 35'L is notched at 36 to receive the upturned web 37 of the sheet 11. The central portion '380i the saddle block 35 is constructed so as 'seams tov close the .latter contiguous to the ock 35 to the inside 36 of theY pan, in combination with the above described,

binding or saddle block, through which asses the binding bolt 34, serves to form a Joint at the top of'the car that is watertight, and atA the same time holding the parts in place without undue pressure being brought to bear on the sheets themselves.

From the lforegoing description taken in connection with the drawings, it is. thought that the many advantages herein represented aie readily seen without further elaboration.

I claim: l

l. A metallic rooting for cars comprising a. plurality of metal sheets rovided at their meeting edges with interloc in o beadsforming seams,.and certain of saidasheetsbeing provided with-integral seam-closing members arranged to be bent over the ends of the eaves 'ofthe car bod 2. A-metallicroofiiig for carscomprising a plurality of-metal sheets rovided at their meeting edges with interIoc ing beads which are cut away contiguous to the eaves of the car body to provide clearance along the roof contiguosato the' eaves, certain of said sheets bein provided with integral seam closing meners arranged to be bent over the ends of the seams formed by said beads to1 provide for closing the seams contiguous to the eaves of the car body.

In testimony whereof I hereunto ailix my signature infthe presence of two witnesses.
